Worried about my daughter's future

We are married on 1999 and since then Iam facing dowry issue from my mother in-law and after 10 years we had a baby by treatment, and even then I used to receive lots of hatred to my baby and me. But I kept quiet due to family pride and respect.from 2023 again the same is repeating due to immense credits made by my husband. He is a government employee, by showing that he took lots and lots and amount from others with our any thought. Now he is again mentally harrassing me for money and my daughter for supporting me.She is minor now (15 years old) I'm very much worried about my daughter's future.He borrowed money to pay her college fee from her brother and now his brother also started to mentally harrass my daughter in many ways. Please suggest me what can I do to protect my daughter's career, I tried to talk with him about his brother. But he is simply deniying to talk and giving waring to me saying that you pay the fee, I'm not a working women.kindly suggest what laws will help and and what action can I take against my husband his mother and his brother in this case.
